I'm not sure what I did wrong my G3F.obj does not quite match G2F (the grey G2F doesn't match the flesh base of G3F) even with G2F parameters dialed to 100% and mesh set to base and 0. (I left Render Sub D as 1 as you didn't mention it). When I try to load the objs as morphs it says the geometries don't match.

Many thanks in advance. I don't know how you worked out how to do this, but if I can get it to work it will be a godsend!
